[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0030] It should be noted that the directional words such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.
[0031] Please refer to Figures 1, 2 and 3, Figure 1 is a schematic diagram of the overall structure of the roof drainage device in an embodiment of the present application; Figure 2 is a front view of the roof drainage device shown in Figure 1; Figure 3 is a schematic diagram of the corrugated roof plate and the eaves structure in the roof drainage device shown in Figure 1.
[0032] The roof drainage device provided in the embodiment of the present application is used to be arranged on the roof of a rail vehicle body. The roof drainage device includes a drainage top plate 10, a water guide sealing plate 20 and a rain eave structure 30.
[0033] The drainage top plate 10 is used to guide rainwater to both ends of the vehicle body along a first direction. The first direction may be a longitudinal direction, i.e., the length direction of the vehicle body, specifically referring to the longitudinal arrow shown in FIG1 . The drainage top plate 10 may be provided with a drainage groove 11 extending in the longitudinal direction, and the drainage groove 11 is used to drain rainwater to both ends of the length direction of the vehicle body.
[0034] The water guide seal plate 20 is installed on one side of the drainage top plate 10 close to the air conditioning platform 40 on the vehicle body, or in other words, the water guide seal plate 20 is installed between the drainage top plate 10 and the air conditioning platform 40 on the vehicle body. The water guide seal plate 20 is used to block the rainwater on the drainage top plate 10 from flowing to the air conditioning platform 40, and is used to guide the rainwater on the drainage top plate 10 along the second direction to the rain eaves structure 30. The second direction can be the horizontal direction, that is, the width direction of the vehicle body, specifically refer to the horizontal arrow shown in Figure 1.
[0035] It can be seen that the water guide sealing plate 20 can not only block the rainwater on the drainage top plate 10 from flowing to the air-conditioning platform 40, thereby avoiding the risk of leakage at the air-conditioning sealing ring 42 caused by the backflow of rainwater to the air-conditioning platform 40 and leakage into the vehicle, but also can guide the rainwater on the drainage top plate 10 along the second direction to the eaves structure 30, and finally use the eaves structure 30 to discharge the rainwater along the first direction to the two ends of the vehicle body, thereby reducing the risk of leakage or the risk of service life caused by long-term backflow of rainwater from the windshield outside the through-channel due to the direct discharge of rainwater from the end of the vehicle body to the top of the windshield outside the through-channel.
[0036] The eaves structure 30 is installed on both sides of the roof of the vehicle body, and is used to drain rainwater to both ends of the vehicle body along a first direction. That is, the eaves structure 30 is arranged on both sides of the roof, and the eaves structure 30 extends along the first direction, so as to facilitate draining rainwater on the roof from both sides of the roof to both ends of the vehicle body.
[0037] Compared with the traditional method of directly draining rainwater to the air-conditioning end or both ends of the vehicle body, the roof drainage device provided in the embodiment of the present application, on the one hand, guides rainwater to the two ends of the vehicle body along the first direction through the drainage top plate 10, thereby avoiding the safety problem of electrical equipment caused by excessive rainwater on one side; on the other hand, the water guide sealing plate 20 blocks rainwater from flowing to the air-conditioning platform 40 on the roof, and guides rainwater to the eaves structure 30 along the second direction, and finally uses the eaves structure 30 to drain rainwater to the two ends of the vehicle body along the first direction, effectively reducing the amount of water accumulated between the bottom of the air-conditioning unit 41 and the top plate of the air-conditioning platform 40, thereby avoiding the risk of leakage into the vehicle caused by the backflow of rainwater to the air-conditioning platform 40, and at the same time, it also reduces the risk of leakage or service life caused by long-term backflow of rainwater to the windshield outside the through-channel due to rainwater directly dispersing from the end of the vehicle body to the top of the windshield outside the through-channel.
[0038] In addition, the roof drainage device has simple process, easy installation, good reliability and is maintenance-free.
[0039] In some embodiments, the drainage top plate 10 is provided with a plurality of drainage grooves 11 spaced apart along the second direction, each drainage groove 11 is arranged in parallel and extends along the first direction, and each drainage groove 11 is provided with a water outlet facing the water guide sealing plate 20 .
[0040] Of course, according to actual drainage needs, a preset distance can be set between the water outlet of the drainage trough 11 toward the water guide seal plate 20 and the water guide seal plate 20, that is, after the rainwater is discharged through the water outlet of the drainage trough 11 toward the water guide seal plate 20, it needs to pass a certain distance before being blocked by the water guide seal plate 20. The structure between the water outlet of the drainage trough 11 toward the water guide seal plate 20 and the water guide seal plate 20 is high in the middle and low on both sides, which is conducive to the rainwater being discharged to the eaves structure 30 along the second direction.
[0041] Furthermore, a water guide groove extending along the second direction is opened between the water outlet of the drainage groove 11 toward the water guide sealing plate 20 and the water guide sealing plate 20. The water guide groove is an arc-shaped water groove. In this way, rainwater from the water outlet of the drainage groove 11 toward the water guide sealing plate 20 can flow into the water guide groove extending along the second direction, and flow to the eaves structure 30 after being drained by the water guide groove. The water guide groove mainly plays a diversion role when the amount of rainwater on the roof is small. When the amount of rainwater is large, the drainage function is mainly achieved through the blocking and diversion effects of the water guide sealing plate 20.
[0042] In some embodiments, the drainage top plate 10 is specifically a corrugated top plate, and each trough of the corrugated top plate forms a plurality of drainage grooves 11 extending along the first direction. In this way, each trough of the corrugated top plate can be used to guide rainwater to both ends of the vehicle body, which has a simple structure and avoids safety problems of electrical equipment caused by excessive rainwater on one side.
[0043] In some embodiments, the corrugated top plate is an arc-shaped plate body of an integrally formed structure, and the corrugated top plate is a structure that is high in the middle and low on both sides, so that rainwater flows down along both sides to improve the drainage efficiency. The water guide seal plate 20 is also an arc-shaped plate body of an integrally formed structure, and the height of the water guide seal plate 20 should be greater than the thickness of the corrugated top plate to prevent rainwater from easily passing over the water guide seal plate 20 and entering the air conditioning platform 40 when the amount of rainwater is large.
[0044] In order to facilitate the installation of the water guide sealing plate 20, a side of the drainage top plate 10 close to the air conditioning platform 40 is provided with an end top curved beam, and the water guide sealing plate 20 is welded to the end top curved beam.
[0045] In some embodiments, the height of the eave structure 30 gradually decreases from the middle to both ends.
[0046] That is to say, the height of the rain canopy structure 30 on either side of the roof is a structure that is high in the middle and low at both ends, which makes it convenient for rainwater to drain to the two ends of the vehicle body.
[0047] In some embodiments, the eave structure 30 is in a bent shape, and includes a plurality of continuous bent bodies to form a rain gutter 31 for draining rainwater.
[0048] The cross-sectional shape of the rain gutter 31 includes but is not limited to a semicircular shape, a polygonal shape, etc. On the one hand, the rain gutter 31 can accommodate a certain amount of rainwater, and on the other hand, it can quickly drain the rainwater to both ends of the vehicle body.
[0049] In some embodiments, the rain canopy structure 30 is symmetrically arranged on both sides of the roof of the vehicle body.
[0050] In some embodiments, the eaves structure 30 and the roof of the vehicle body are integrally formed. For example, the eaves structures 30 on both sides of the roof can be integrally curled structures of the edges on both sides of the roof.
[0051] With the roof drainage device arranged as above, the process of roof drainage is as follows: the corrugated roof plate used forms a plurality of longitudinal waterways to guide rainwater to the ends for discharge; when rainwater flows from the corrugated roof plate to the air conditioner, it is blocked by the water guide sealing plate 20, and the rainwater changes direction to flow to the eaves structure 30 on both sides, and then is discharged to the two ends of the vehicle body along the eaves structure 30.
[0052] The above-mentioned roof drainage device has simple process, easy installation, good reliability and is maintenance-free. It not only avoids the risk of excessive water accumulation under the air conditioner causing poor drainage or water seepage into the car, but also reduces the risk of leakage or service life risk of the windshield outside the through-channel due to long-term rainwater backflow.
[0053] A rail vehicle provided in the present application includes the roof drainage device described in the above specific embodiment; other parts of the rail vehicle can refer to related technologies and will not be elaborated in this article.
[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0055] The roof drainage device and rail vehicle provided by the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the scheme and its core idea of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the present application.
